WEWERKA, 0F BALTIMORE MARYLAND GASOLINE RESERVE SUPPLY DEVICE Application led September 5, 1929. Serial No. 390,611.

The present invention relates to improvements in gasoline reserve devices and has for an object to provide for maintaining always on hand a quantity of gasoline or other` fuel l normally cut oft' from the carburetor but adapted to be connected to such carburetor in the event that the main gasoline supply becomes inadvertently exhausted.

Although some attempts have been heretofore made to provide reserve for the emergency referred to, so far as we are aware no practicable device has yet been suggested whereby the reserve tank is so connected with the fuel system of the automobile that such peserve tank is alwaysreplenished with the It is a further object of the invention to provide an improved valve and pipe arrangement between the reserve tank and the fuel system whereby the reserve tank will at all times be kept full of fuel and will be relled automatically after each emptying operation.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

Figure 1 is a side elevation of a combined vacuum t'ank and reserve tank with the improved valve and pipe assembly shown in connection therewith. v

Figure 6 is a. side view with parts broken w awa and parts shown in section and illustratmg a slight modification.

Referring more particularly to the drawings 7 designates a vacuum tank of the kind usually found on automobiles. The vacuum tank is connected by pipe line 8 with the fuel tank usually placed in the rear of the automobile and at a lower level than the carburetor. The vacuum tank 7 functions to raise the fuel from the main tank to the vacuum tank whereby the fuel may iiow by gravity out to the carburetor. The out-flow pipe is indicated at 9 and in accordance with the invention this out-flow 'pipe 9 connects with one branch 10 of a valve casing 11 containing the rotary plug valve l2y which is turned by means of a handle 13 on the exterior of the valve casing. A second branch 14 of the valve casing connects by a pipe 15 with the bottom of the reserve tank 16 and may be placed along side the vacuum tank 7. A third branch 17 of the valve casing connects by a pipe 18 with the carburetor (not shown).

The branches 10 and 14 are preferably diametrically opposite one another, the branch 10 being disposed downwardly and the branch 14 projecting upwardly. rlhe third branch 17 referably comes od the valve casing lateral y at an intermediate portion of the casing 11 and may take the form of an elbow.

The plug valve l2 is provided with two ports, 19 and 20. These ports are to opposite sides of the center of the valve, the port 19 being closer to the center than the port 2() and the port 19 being a straight-through port to set up communication between the lower and upper branches 10 and 14. The

port 20 is so shaped that it may set up comy munication between the lower branch l0 and the lateral branch 17, when the valve is in the position shown in Figure 2; or it may set up communication between the upper branch 14 and the lateral branch 17 when turned to the position shown in Figure The lower branch 10 is provided with two passages, 21 and 22. The passage 22 is a free uninterrupted passage. The passage 21 is rovided with a downwardly closing check va ve 23.

In the use of the device, the parts are northe pipes 9 and 18 to such carburetor. Inso` doing this fuel will traverse the free passage 22 in the lower branch 10 and the port 20 of the valve 12 which is in register with the passage 22 and the lateral branch 17 Now at the same .time the fuel will pass through the branch 21 raising the check valve 23.

` the port 19 of the valve and through the branch 19 and pipe 15 into the reserve tank 16. A reserve of gasoline will' accordingly be built up in this tank 16. The reserve supply cannot escape as the check valve 23 closes downwardly. A

Should the supply of gasoline in the main tank become exhausted through lack of attention, the handle 13 may be rotated to cause the valve 12 to be shifted to the position shown in-Figure 3. f In such position the port '19 is entirely masked and the lower branch 10 is cut of from all communication, either with the reserve tank or the carburetor.A

However, the-reserve tank 16 is placed in open communication with the branch 17- through the port 20 and the reserve gasoline may iow to the carburetor, thus affording a reserve supply which will enable thevehicle to gain the next service station.

Now when the main tank supply is replenished at such service station, the valve 12-will be turned by hand back to its initial position shown in Figure 2. The arrangement is such` that it is compulsory to do this, or 'it-will become compulsory when the reserve .tank supply is exhausted.. .When such valve 12 assumes the initialposition and the flow of gasoline again talfesplace through the vacuum tank 7, the reserve tank 16r is automatically re lenished through the port 19 so that there ling of the reserve tank does not depend upon the attention of the operator but it is a necessary result ofthe operation of the device constructed according tothe present invention.

The device shown infFigure' 6 differs from that shown in the other figures merely in that the invention is shown applicable to fuel systems in which thevacuum tank is dispensed with and a gas pum used. In this mstance` the pipe 9 exten s ltoa asoline ump and the gasoline' pump forces t e gasoine from the main supply -tank tothe carburetor and through the im roved valve device, to the reserve tank 16, tv 'ch contains a' float 24 co-o eratng withthe levers 25 for raising the v ve plun er 26 against the seat 27 depending from'the' aille plate' 28. g

This fuel will pass also through It -will be noted that the arrangement of passages is such' as to make` it impossible' to draw fluid from the vacuum tank or main supply without placing the reserve tank in the line for refilling.

. In `Figurest and 5, one type of rotary valve is shown, but it will be understood that a ta pering plug type valve may be substituted. It will also be understood that provision may be made for operating the valve from the dash or instrument board of the vehicle, as, for instance, by couplingv a rod to the handle 130i the valve.

i It is obvious thatl various changes and modifications may be m'ade in the details of construction and design of the ,above specifically described embodiment of this invention Without departing from the spirit thereof, such chan es' and vmodifications being restricted ony by the scope of the following claims.

What is claimed is: y

1. In combination with a fuel line, a reservel tank, a valve casing in said fuel line having an inlet branch with a plurality of passages, an outlet branch and a branch to the reserve tank, a check valve in one of said passages. opening toward the tank, and a rotary valve in the casing having a pair of ports,

said ports being disposed on opposite sides of the center of the'valve, said valve adapted in one position to place the check valve passage in communication with the tank and.to open the fuel line and in a subsequent position to close the fuel line and open the tank to the carburetor. v

2. In combination with a fuel line, .a reserve tank, a valve casing in said fuel line having a lower inlet branch with a plurality of passages, an outlet branch and an upper branch to the tank, a check. valvev in one of -said passages opening toward the tank, kand a rotar valve in the casing having'apair of ports o isposed on oppositesides, of the center of the valve, one.y of saidA ports being a straight-through portv and closer tothe cen- 'ter vof the valve than the other port, said straight-through port ada ted to setup communication between the lower and upper branches in one position of the rotary valve,

said .other port being at an angle to thel straight-.through port and adapted to set up communication between the inlet and the outlet branches in one position of the rotary valve and to set up communication between the upper and outlet branches in another position of the rotary valve.
